Nah, probably not. The only time a player should be surprised by the inclusion of a wild in a slot machine is if the slot in question is a three-reel classic-style game. Otherwise, yeah. Your 5-reel game’d better have at least the standard wild capable of substituting to make up those winning combinations. I mean, the odds are already well stacked against the player in slots; you can’t take away the wild symbol!
Even more than you’d guess. Along with evermore common riffs on the standard wild such as sticky wilds and stacked wilds – you can see our separate pages devoted to these – a wild symbol may do even more for the player than “merely” act as a wild card to create wins.
A wild may also provide a bonus multiplier on any wins it helps make up, and can also multiply unto itsle in such a win. So if a wild symbol is automatically worth 3x the regular payout on wins, landing two wilds on that active payline should be valued at 9x the payout. You can see the possibilities here…
Just look at this page. Literally thousands of titles on this website and even (a few) more online have wild symbols. In fact, we’d challenge you to find a 5-reel slots game worth playing that *doesn’t* have wilds in it!
